I'm a doctor and I've grown increasingly frustrated with the products being targeted at women for menstrual cycles. Labels are now boasting "alternative facts" quite frequently. If you're trying to go natural and avoid using anything toxic or irritating you can easily be misled. I was looking for a product that I could suggest for patients who are sensitive to chemicals, at risk for genitourinary issues, etc. I decided to try the reusable sanitary napkins for myself since a recent irritation developed from using a leading menstrual pad manufacturer. I washed the pads prior to use and allowed them to air dry. I used them with absolutely no leakage during the day or night. I do recommend using the XL size for overnight since it is longer. I use the smaller sizes I previously ordered as daily panty liners. These don't require much effort to clean unless you are on your menstrual cycle. When on your menses, you will need to rinse and/or soak them prior to tossing them into the washing machine. Overall, I like and enjoy using these products. This is my 2nd purchase from this manufacturer. I have not experienced any irritation whatsoever. My work days are usually 12 hours long and I can wear these smaller ones as panty liners without any issues. My napkins came with a nice carrying pouch that zips and fits neatly into my hobo bag purse.
